Abstract
A simple synthesis method has been developed to improve the structural stability and storage capacity of MXenes (Ti3C2Tx)-based electrode materials for hybrid energy storage devices. This method involves the creation of Ti3C2Tx/bimetal-organic framework (NiCo-MOF) nanoarchitecture as anodes, which exhibit outstanding performance in hybrid devices. The 2D Ti3C2Tx nanorods are combined with NiCo-MOF nanoflakes through hydrogen bonding to create 3D Ti3C2Tx/NiCo-MOF composite. The electrochemical characteristics of Ti3C2Tx@NiCo-MOFs nanocomposite were measured. Due to enhancements in charge transfer and redox properties, the composite electrode consisting of Ti3C2Tx/NiCo-MOFs demonstrated a specific capacity of 1635.1 Cg−1, significantly surpassing that of pure NiCo-MOFs (844.5 Cg−1). Additionally, the hybrid supercapacitor device (Ti3C2Tx/NiCo-MOFs//AC) showed a specific capacity (Qs) of 222.53 Cg−1 with an energy density (Ed) of 56 Wh/kg and a power density (Pd) of 2800 W/kg by using KOH as an electrolyte. The device achieved an impressive capacity recovery rate of 86.7% after being tested with up to 5000 charging and discharging cycles. This study opens new ways to make safe and reliable supercapacitors using environmentally friendly materials. The findings underscore the significant potential of Ti3C2Tx/NiCo-MOF in advancing the field of high-performance hybrid energy storage devices.
